Make sure the opening <noinclude> begins on the same line as the last character of the template code (or text), and not on a new line. Otherwise, extra space will be inserted below the template when it is used, which is usually not wanted.

If the template is already protected, ask an administrator to do this, or request an edit by using {{editprotected}} on the template’s talk page. If documentation, categories and interwiki links already exist in a section enclosed within a <nowiki> element, move them into the documentation subpage, as it is best not to have documentation split across two separate pages.

Limitation

A pipe character in the documentation page which is not inside double or triple braces or double brackets disturbs proper functioning of this template, because the content of that page is assigned to a template parameter. Use &#124;<code> instead.

If the documentation contains includeonly or noinclude tags within nowiki tags, replace the "<" with "&lt;".
